We're going to turn now to tiger woods. He won again over the weekend. Moving him one step closer to number one in golf. After his personal life exploded a couple of years ago, some wondering if he could come back. Reporter: He didn't just win, he roared. The man who for years was the world's best golfer was back at the top of his game sunday, winning the wgc cadillac championship, his second pga tour win this year. In your mind who is the best player in the world? Well, you always have to believe in yourself. You have to have the inner belief that you are the best. Reporter: If he wins his next tournament, he would find himself ranked numberone. What matters to tiger, think, is more what gets you to number one, that is winning. Reporter: But the 37-year-old has not just seen success on the tour recently. He's found redemption off of it. Last month, invited to play a round with president obama. He can certainly chip and putt. Reporter: After a series of missteps beginning with the headline-grabbing revelation in 2009 that he cheated on his wife, elin nordegren. I am deeply sorry. Reporter: His life went into a tail spin. Evaporating endorsement deals. A sex addiction treatment program. He became tabloid fodder. Speculation of whether he would get back together with his ex-wife. He suffered a leg injury on returning to golf. His ranking plummeted to 58th worldwide. On sunday, that all seemed to melt away. Now with in latest win, tiger is closing in on sam snead, the career leader in tour titles at 82. He could regain the number one in two weeks. I have a feeling the ratings will be high on that date. And he loves bay hill. He always plays well there. Yes, yes.
